ELECTRIC DROP-LIGHT.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed December 29, 1917. Serial No. 209,556.

To all whom it may concern:

Be it known that I, ANDREW A. WINER, a citizen of the United States, residin at Ocala, in the county of Marion and state of Florida, have invented new and useful Improvements in Electric Drop-Lights, of which the following is a specification.

This invention relates to electric drop lights, and the object is to provide an adjustable device by means of which the usual lamp cord connected with a porcelain ceiling block may be adjusted to any length for placing the light or lamp in the most convenient position above the desk or table where the light is to be used.

In connection with the flexible lamp cord I employ a suitable pulley and block for mounting the latter, a counterbalancing device, a hook memlber flexibly and slidably connected with the lamp cord and adapted for connection with an article of furniture or any stationary object, and with a ferrule or the like, the latter permitting the cord to be looped for effecting the desired adjustment.

In the drawings- Figure 1 is a view in side elevation showing the lamp and adjusting device suspended in operative position.

Fig. 2 is a detail in section showing the manner of carrying the wire through and around one of the pulley blocks.

Fig. 3 is a detail of the lower pulley and counter balance.

The ceiling block of usual construction is shown at 10, and the lamp cord as a whole is designated 12. this cord passing through apertures 13 and 14 in the longer side member or plate member 15 of the pulley bracket or block designated as a whole by the number 16. Within this member 16 is a pulley wheel 17 around which the cord passes after having passed .over a pulley wheel 18 forming a part of the counterbalancing device. The 'block of the pulley 18 carries a freely moving stem or the like shown at 20 threaded at its lower Copies of this patent may be obtained (or end and engaged by a nut 21, retaining in position a plurality of weights of any required number in order to suitably counteiibalance the device.

In the drawings I have shown three of these weights, the upper and lower members being designated respectively, 22 and 23 and the intermediate weights being shown at 24. These weights 24 may be of various sizes, representing two, three and four ounces.

The cord 12 after having passed over pulley 18 and the upper pulley mentioned, extends to the lamp socket 25 carrying a lamp 26.' A ferrule 28 is slidable on the cord and is flexibly connected by means of a chain 29 with a hook 30 having a sharpened point for engagement with any convenient stationary object, as an article of furniture or a door frame. The cord passing through the ferrule 28 extends thence to a point where it is engaged freely by a hook 31 connected with a ferrule 32 and adapted to have swinging pivotal movement with reference thereto.

It will therefore be observed that by adjusting the various lengths of cord with reference to the pulleys and the devices 28 and 32, any required adjustment may be secured.

What is claimed is:

In a device of the class described, an apertured block and a pulley carried thereby, a cord passing through one of the apertures of the block to the opposite side of said block, then along the surface of the block to another aperture and through the latter, a counterbalance and a pulley connccted therewith, said cord passing around the pulley first named and around the second named pulley, and a plurality of slidablc members carried by the cord, an engaging device flexibly connected with each slidable member, and a lamp socket connected with one of the free ends of the cord.

In testimony whereof I affix my signature.
